Domain, Range, Evaluate Function Notation

Which graph is not a function?

• Graph 1
• Graph 2
• Graph 3
• Graph 4

If a question asks you to find f(2), what does that mean?

• Let x = 2

• Let y = 2

Evaluate f(-2) if f(x) = x + 3

• -1
• 1
• 5
• -5

What is the DOMAIN of this graph?

• x < -3

• x ≤ -3

• x > -3

• x ≥ -3

What is the range?

• -4 < x ≤ 5

• -4 ≤ x < 5

• -3 < y < 3

• -3 ≤ y ≤ 3

How would you write y = 2x - 3 in function notation?

• y = 2x-3

• f = 2x - 3

• f(x) = 2x-3

If f(x) = 2x + 1, find f(1).

• f(1) = 1

• f(1) = 4

• f(1) = 0

• f(1) = 3

What is the domain of the function graphed?

• x < 5
• x ≥ 1
• x > 0
• All real numbers

What is f(1)?

• 1
• 5
• 0
• 4

What is the Range?

• y ≥ 6

• -10 ≤ y ≤ 6

• -10 ≤ x ≤ 6
